Gemini agent handoff abuse can leak secrets and alter pull requests
Source headline: Gemini Agent-to-Agent Attack Method Exposed Secrets, Enabled Pull Request Tampering
Intelligence Summary
A reported technique can turn a low-privilege Gemini Agent into a stepping stone for higher-privilege actions. By crafting a malicious hand-off instruction, an attacker may pass hidden or “handoff” content to a privileged agent. The injected content can then be used to expose secrets that the privileged agent can access. The same mechanism could also tamper with pull requests by manipulating what the privileged agent submits. Teams using agent-to-agent workflows should audit handoff handling, limit agent permissions, and review logs and review-gating controls.
